    • PURPOSE: To obtain the bead of high quality at the seam terminal by selecting adequately the welding current, welding voltage and welding speed at the seam terminal welding time.
      CONSTITUTION: The stationary part is welded under steady welding conditions, for instance, of the current I
      0 : 500A, voltage: V 25V, speed S
      0 : 4m/min in the seam welding of UOE steel pipe. When approaching to the terminal part it is transferred to the terminal welding conditions of causing no arc blow of, for instance, current I
      1 : 170A, voltage V
      1 : 17V and speed S
      1 : 1 m/min at the time T of for instance 1W1.5 sec by an integrating circuit. In case of performing the high speed welding of MIG, MAG, TIG, etc. this method can be applied for every field which needs the control of bend shapes.

    • 目的:通过在焊缝端子焊接时间内充分选择焊接电流,焊接电压和焊接速度,在焊接终端获得高质量的焊珠。 规定:在UOE钢管的缝焊中,固定部分焊接在稳定的焊接条件下,例如电流I0:500A,电压:V 25V,转速S0:4m / min。 当接近端子部分时,转移到例如电流I1:170A,电压V1:17V和速度S1:1m / min的电弧不发生的终端焊接条件,例如在时间T,例如1- 1.5秒由积分电路。 在进行MIG,MAG,TIG等的高速焊接的情况下,该方法可以应用于需要控制弯曲形状的每个场。
